Practice, practice, practice

If your kids are a little rusty on the language arts basics, or they just need some practice to reinforce what they are learning, http://www.iknowthat.com/ has a great game for punctuation practice called Punctuation Paintball. Basically an unpunctuated and uncapitalized sentence pops up on the screen and you have to choose the correct punctuation and shoot it at the sentence to correct it. There are 3 levels of difficulty, depending on how many punctuation elements you wish to include (Capitalization, periods, commas, question marks, exclamation marks, and quotation marks for the advanced level). You are led to a free registration screen, but you can proceed without registering.

The other gem on the site is Leon's Math Dojo, which is a fast-paced drill for addition, subtraction, multiplication, or division. The lowest level of multiplication drill (what we use it for) is factors through 12, but the answers are multiple choice. I like this drill better than the others I've found because there's no typing involved here. Why is this important? The drills can proceed as quickly as your child knows the answer, not as quickly as your child can type.

Of course you can upgrade to premium content, but the basics here are pretty good, and you can register for free to keep track of scores. Dig around by grade level on the main page. I stumbled upon a preposition drill that was quite addictive. Definitely worth checking out!
